Transgender

Transgender is a term which refers to a person who has a gender that does not align with their sex.

This is an umbrella term which encompasses terms such as non-gender, androgynes, transexual, etc.

Because the term is so broad, it is often used in reference to a group as opposed to a specific individual.

Example:

Jake: “You should come along to our Transgender Support group, Liam.”
Liam: “Are you sure? I don’t know if I’m Transgender... You know I’m non-gender, right?”
Jake: “LOLWUT. Non-gender falls under the term Transgender, you silly sausage.”
